Intelligent bolt monitoring system for fault detection of machine tool spindle transmission part

Abstract

The invention discloses an intelligent bolt monitoring system for fault detection of a machine tool spindle transmission part. The intelligent bolt monitoring system includes a plurality of intelligent bolts installed in the key connection positions of the machine tool spindle transmission part, wireless transmission units, a signal receiving unit, a data processing unit, an alarm unit and a machine tool servo unit, wherein triaxial acceleration sensors for vibration signal acquisition are arranged in the intelligent bolts, and the wireless transmission units are arranged inside the intelligent bolts and send vibration signals; the signal receiving unit is located in a machine tool control system and used for receiving the vibration signals; the data processing unit is located in the machine tool control system, and calculates and analyzes the vibration signals; the alarm unit is electrically connected with the receiving data processing unit to issue an alarm; and the machine tool servo unit is electrically connected with the receiving data processing unit to control emergency shutdown of corresponding equipment. The intelligent bolt monitoring system for fault detection of the machine tool spindle transmission part has the following advantages and effects that the ubiquitous bolts on a machine tool are endowed with the perception function, the working status of the machine tool spindle transmission part can be effectively monitored, the quality of machined products is guaranteed to the maximum, the running efficiency of the machine tool is improved, and machine and personnel safety is guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical equipment state monitoring, in particular to an intelligent bolt monitoring system used for fault detection of machine tool spindle transmission parts. Background technique [0002] The biggest feature that distinguishes intelligent machines from traditional machines is that they can monitor and analyze their own operating status in real time like humans, intelligently make optimal decisions, and maximize product quality, thereby improving work efficiency and protecting the safety of machines and personnel . As the "rice of industry", bolts are also an essential part of intelligent machines. If the bolts of the machine also have the ability to monitor and analyze, it will provide an effective solution for the intelligentization of the machine. [0003] During the normal operation of the machine, its vibration signal is stable and fluctuates within a certain range; when the machine is overloaded or wor...

Problems solved by technology

[0006] However, for intelligent machines, vibration monitoring is the most convenient and mature fault detection method, which is applied to real-time monitoring and diagnosis of machine running status. However, there is no intelligent bolt monitoring system for monitoring vibration signals at home and abroad.
